Idea for unbotting BGs

I have been trying to think of a simple and achievable way that Blizzard could create a relatively bot free environment.

Human:
1. Human character dies in BG
2. Goes to Graveyard
3. Wow displays a 5 alpha captcha on the ground
4. You type it in
5. You resume play

Bot:
1. Bot character dies in BG
2. Goes to graveyard
3. WoW displays a 5 alpha captcha on the ground
4. It doesn't get typed in
5. After 30 seconds of not rezzing the bot is kicked from BG.

Note 1 - the captcha isn't displayed via a popup, but is displayed in game so that it may require you to use the mouse to move your PoV to see the characters.
Note 2 - Toons booted from BGs using this method are not account penalised, but are not allowed into BGs for 30 minutes (aka deserter debuff).

Looking for feedback on if it would work (in game terms), as it would be something fairly easy to implement in programming terms.

A better solution would be mixing this with another idea I've seen, that being the captcha w/e posted at the beginning of every 5th game or so, rather than when you die. Failure to complete the captcha makes your account unable to gain rewards (honor / xp) for the next 5 bgs. Simple.

Not all rezzes are 30 seconds in length, what happens if you dont type it in fast enough.
If this were to be adopted then why not use the account authenticator instead. This would prevent botting, buying bgs from companies that sell them and encourage the use of authenticators.

1. Human character dies in BG
2. Goes to Graveyard
3. Wow displays a 5 alpha captcha on the ground
4. You type it in
5. You resume play

6. Human character dies in BG

9. You type it in
10. You resume play
11. Human character dies in BG
12. Goes to Graveyard
13. Wow displays a 5 alpha captcha on the ground
14. You scream "FUCK THIS SHIT!!"
15. You leave the BG

I do not believe in a system which basically criminalizes real players. Also it wouldn't be that hard to figure a way around this. If bots can read memory locations and find the coordinates of, let's say a fishing bobber, how long will it take before they figure how to load a texture and parse the details into something usable?

Its not that bad an idea, Some changes i would say are only show the captcha if the rezzes are longer than 15 seconds. Another is after 2 successful captcha completions (character dies twice and correctly completes the captcha messege during both deaths) The captcha no longer appears for that player. This way legit players are not constantly worrying about getting kicked and it doesnt become an annoyance.

Make it so you have to type a 12 letter phrase in under 4 seconds, or you get banned from the game for 24 hours. if you want to continue playing, phone up the terrible customer service, be put on hold for an hour, then have them hang up on you.
